Abstract
According to an embodiment, a management device includes a calculator and a notifier. The calculator calculates a time offset for each of a plurality of master devices each performing, when a measured time reaches a certain time, time synchronization with a slave device, which is a management target, at the measured time. The notifier notifies each master device of a change notification causing the master device to change the measured time in the master device to a time obtained by offsetting the measured time with the time offset.
